Dudleya blochmaniae

A tiny summer-dormant Dudleya of coastal bluffs and grassland from San Luis Obispo to northern Baja California, surviving the dry season as an underground corm. Water in winter and spring, then let the leaves wither and keep it dry until autumn rains.

Where it grows wild

Open, rocky coastal slopes and grassland, often on serpentine or clay soils, in coastal scrub; the leaves die back in summer and the plant persists as a corm.

Mostly below 450 m (median 64 m); subsp. insularis grows on Santa Rosa Island bluffs at 3–90 m.
